----------------------------------
Summary: Only FQDN is accepted for OM rpc address in secure
environment
Key: HDDS-1355
URL: https://issues.apache.org/jira/browse/HDDS-1355
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Elek, Marton
While the scm address can be a host name (relative to the current search
domain) if the om address is just a hostname and not a FQDN a NPE is thrown:
{code}
10 │ OZONE-SITE.XML_ozone.om.address: "om-0.om"
11 │ OZONE-SITE.XML_ozone.scm.client.address: "scm-0.scm"
12 │ OZONE-SITE.XML_ozone.scm.names: "scm-0.scm"
{code}
{code}
2019-03-29 14:37:52 ERROR OzoneManager:865 - Failed to start the OzoneManager.
java.lang.NullPointerException

{code}
I don't know what is the right validation rule here, but I am pretty sure that
NPE should be avoided and a meaningful error should be thrown. (and the
behaviour should be the same for scm and om)
